You can make a story a "Sticky Post" to keep it at the number one position on your FeedsyWeb and App (and FeedsyMail):

1. Open edit screen of the story.
2. Scroll down to the Publish section.
3. Click on "Edit" next to "Public".
4. Tick "Stick this post to the front page"
5. OK

Note: you will need to remind yourself to make it "unsticky" once you do not wish the story to appear there anymore:

1. Open edit screen of the story.
2. Scroll down to the Publish section.
3. Click on "Edit" next to "Public".
4. Un tick "Stick this post to the front page"
5. OK
